Abstract: An antenna assembly includes a substrate (52) having front and back surfaces (52a, 52b) thereon and a plurality of through-holes (70) therein, along with a solder pad (68) on the back surface of the substrate. An input cable is also provided, which is attached to the back surface of the substrate. The input cable includes an outer conductor (62), which contacts the back surface of the substrate, and an inner conductor (56), which extends at least partially through a first of the plurality of through-holes and is electrically connected to the solder pad. A metal trace (e.g., 50-ohm trace) is provided on the front surface of the substrate. The metal trace is electrically connected to the solder pad by electrically conductive plating in a second of the plurality of through-holes (see Fig. 6a).
